Solvent effect on the hammett reaction constant for the electroreduction of substituted benzophenones

Journal of Physical Organic Chemistry, 1992
AbstractSolvent effects on the Hammett ρ value for the cathodic reduction of substituted benzophenones were determined. The electrochemistry of a series of 11 compounds was studied in acetonitrile, acetone, dimethyl sulphoxide, propylene carbonate, N,N‐dimethylformamide, N,N‐dimethylacetamide, N,N‐diethylformamide and hexamethylphosphoric triamide.

Hammett-Taft constants of substituted 2- and 4-quinazolinyl groups

Bulletin of the Academy of Sciences of the USSR Division of Chemical Science, 1991
From the chemical shifts of the meta- and para-carbon atoms of the phenyl group in phenylquinazolines the σI and σR0 constants of 2- and 4-quinazolinyl groups were determined. Correlation equations which enable us to calculate the σ constants of various substituted 2- and 4-quinazolinyl groups are proposed.

Towards the unification of the substituent (position) constants in Hammett-Streitwieser equation

Tetrahedron, 1972
Abstract An extension of position constants in the Hammett-Streitwieser equation (HSE) is given. An analogy of interactions between electron repelling group Y and attacking electrophylic agent as well as between electron attracting group and attacking nucleophylic agent is postulated to explain wide applicability of the HSE both the unsubstituted and
